GREENFIELD, Iowa (AP) — Multiple people have died and at least a dozen were injured since a powerful tornado tore through a small Iowa town, carving a bleak landscape of destroyed homes and businesses, shredded trees, smashed cars, and widely strewn debris. The tornado destroyed much of the small Iowa town of Greenfield. Iowa State Patrol Sgt. Alex Dinkla says at least a dozen people were injured amid widespread devastation in Greenfield. Tuesday saw multiple tornadoes, giant hail and heavy rain in several states. The storms and tornado warnings have moved into Wisconsin, including a warning for the state’s capital city of Madison.
